RAID Scanning
A RAID scan read checks all sectors in the data area of drives in an array. If a bad sector
error is found during the scan, it is repaired automatically. Note that some kinds of errors
are repaired automatically by the array even without a RAID scan.
Status
Descriptions
repair possible
• Read error in the data area which are build in RAID 1, 5, or 10 (in-
cluding RAID 1 system array.)
impossible to repair
• Write Error
• RAID management area error
• Drive partition information area error
• Drive recognition failure, etc.
• If many repairable errors are found in one of hard drive which build RAID, that drive
is removed from the RAID, the system will automatically move to degraded mode. The
system will continue to function, but data is not protected in degraded mode, so it is
strongly recommended to immediately replace the erroneous hard drive.
• When running RAID Scanning for the first time, it is strongly recommended to back up
your data on TeraStation in advance.
